A signal conditioning unit is a key part of mechatronic systems. Many specific signals need conditioning before transmitting them to some components of such a system. For instance, the output signals of most sensors are analogue. If these output signals need transmitting to a microprocessor, you must first convert them to a digital form because microprocessors can only receive digital signals. Likewise, most actuators can't operate with digital signals. The digital signals from microprocessors have to be converted to analogue form before being used as an input to the actuator. Various devices are involved in the conditioning of signals for mechatronic components. This course shows you the processes of conditioning and manipulating signals for mechatronic systems and the devices used. You learn why signal conditioning is essential and the processes in conditioning a signal. Examine the internal design and models of operational amplifiers. You will also study the operation of operational amplifiers, with circuit diagrams to show how inverting and non-inverting operational amplifiers work. 

Operational amplifiers constitute a significant component in the manipulation of signals. They are used in combination with other elements to integrate or differentiate signals. This course demonstrates how you can design operational amplifier circuits to add, subtract or compare input signals. You will be shown how operational amplifiers are used in CD players to check the focus of laser light on the optical discs. Furthermore, you will learn how to use operational amplifiers in the filtration of signals. Also, master the parameters that are usually used to specify operational amplifiers. Discover the processes of analogue to digital conversion and the components needed to perform such conversion. This course discusses the effect of Shannon’s sampling theory in the transformation of analogue signals to digital signals. You will be shown the key principles of analogue to digital converters. Then study how signals are represented by the Fourier series and the working principles of the resistor-ladder digital-to-analogue converter. Uncover the essence of multiplexers in signal conditioning. The course ends by introducing you to artificial intelligence (AI) and the roles it can play in mechatronic systems. You will explore how fuzzy logic control systems can help enhance the operation of cooling systems and washing machines.

This course enlightens you on the processes and components involved in the scaling of signals to meet the requirements of the various components of mechatronic systems. Every component has its individual type of signal where it can operate. For example, an induction motor can use analogue signals but not digital ones. But, a stepper motor uses digital signals and not analogue ones. Even if the undesired signals are available, you can always tailor them to the specification of mechatronics components by using devices such as digital-to-analogue converters and operational amplifiers. If you design mechatronic systems or are looking to be a top-notch professional in the field of mechatronics engineering, you will need to understand how to manipulate signals. This course is laid out to support you with knowledge of how you can transform signals to suit the needs of your system.
